Some people here were asking if AVS makes a difference so I did some experiments.

Here's a graph of power consumption vs frequency for a fixed Vdd, the default Static Voltage Scaling (SVS) and AVS.

As you can see, it makes a measurable difference but mostly for the frequencies in the middle. I think that the SVS voltages were probably worked out by drawing a straight line from max to min but actually power is proportional to the square of the voltage so the real curve dips in the middle a bit.

Also, AVS can only make a difference when the phone is not sleeping, when it's sleeping, the Apps CPU (Scorpion) is power collapsed, this means it is completely powered down and draws no power. The modem CPU can also go into a deep sleep mode (TCXO shutdown) to save even more power.

When the phone is idle, i.e. nothing is using the Apps CPU it will go into Power Collapse and use about 10-20mA and AVS can't change this. When the phone is asleep (suspended) the Apps CPU will be Power Collapsed and the modem CPU will use TCXO shutdown and will draw 2-10mA, again AVS has no effect on this.

This means that although AVS makes a measurable difference, it really doesn't make a noticeable difference and if it is at all unstable on your hardware you shouldn't use it.

Where do I get the HD2 port of this ROM? Thanks.

thanks found it.
[Desire Android Development] trinity1:
what is sure is that your reboots are not caused by kernel: I have tried 13-r4, r5 beta 1 and so far I'm with beta 2. No reboots at all.

never had problems with bt, or wifi... Perhaps because I have always performed an oxy

clean installation (full wipe-data factory reset-sd FAT-ext formatting)?
[Desire Android Development] SilverSurger:
Probably this is caused by the high usage of the 3G connection, it sucks the battery dry, there is not a lot to do about it.
[Desire Android Development] :
Does that mean my reboots weren't caused by the kernel either? :D

I pulled the r5-beta2 release for a reason...it's not stable.
[Desire Android Development] mgmate:
Yes, full wipe, even dalvic cache.

I need some help.

When I install an app, my phone suffers a soft-reboot and the app are not installed. It's a really big problem, sometimes when I plug the phone to the PC return to work normally
[Desire Android Development] Shiftone:
Sounds like you didn't do a full wipe before installing oxygen.

Wipe system/data/cache/dalvik
[Desire Android Development] z4ppy:
Not sure if that has been caused by Oxygen 2.1.3 or not but anyway, I've encountered a big problem.

I restarted my phone just before and noticed that my facebook icon that I use didn't load on my home screen. I then proceeded to check my gallery and was greeted with majority of my photos, videos and other images (icons etc) all missing. I restarted my phone and again nothing had changed. So naturally mounted the sd card on my mac and opened it up in Finder, went to where my photos are kept and they're all missing bar like 10 photos/videos from my camera folder and some icons that I use for Launcher Pro etc and are stored elsewhere.

They've all magically just disappeared/been deleted. I've tried mounting sd card via card reader and ran a repair, no change.

My LOST.DIR folder has a heap of files in it and when I click on one and "get info", I get a thumbnail displayed of the photos, videos, icons etc that I'm missing.

Am I right in saying that my sd card has corrupted somehow and I've lost those files? And what would cause this? Given it was working fine before I decided to give phone a restart. Surely isn't an issue with the rom itself is it? I've had this happen before in older Oxygen versions when photos I've taken haven't displayed in my gallery. I'd restart phone and they'd be there.

Just to add. SD-card is formatted with a 512mb Ext2 partition.
[Desire Android Development] :
Yes, it's actually a known Android issue which has existed forever and is still not fixed.

my bet is that its a memory leak in one the apps you are running.

[Desire Android Development] MarcusBremen:
just read the first post by adam_g
[Desire Android Development] :
My bet is it has absolutely *nothing* to do with a memory leak in an application.

I suspect that the issue lies within the dalvik-vm and/or the Android runtime.
[Desire Android Development] Zobat:
hmm, i always clean my dalvik-cache before reporting issues. But you may be right.
[Desire Android Development] roalex:
i have no issues what so ever, 2 days now !

p.s looks like many ppl either dont wipe or mess with the rom, if you dont know what your doing dont remove/add stuff :p
[Desire Android Development] Zobat:
Thats because the dalvik vm cant corrupt your system right?
[Desire Android Development] :
What I was referring to is absolutely nothing to do with the dalvik cache. The dalvik cache is a folder full of dex files which are used by the dalvik-vm.

For info, there is actually no need to wipe the dalvik-cache generally, as the dalvik-vm purges mismatched dex files and updates the cache during boot. All clearing the dalvik-cache does is make your next boot take a lot longer, it doesn't solve any issues.

I referred to the dalvik-vm, which is the java virtual machine which is part of the Android system, and in which all the java code is executed.

After applying the recommended kernel, I cant mount my system partition in recovery, what should I do ?
[Desire Android Development] mastersjef:
The new 2.35 r4 kernel runs flawlessly perfect! nice job again.
[Desire Android Development] :
The recovery kernel is completely standalone, so whatever issue you are having with mounting is nothing to do with any kernel you may have flashed.

Shouldn't you be asking that question in the Oxygen Q&A thread anyway?
[Desire Android Development] milkpowder:
clean install. Wiped dalvik/cache/everything. Apps2SD to class 2 microSD FAT32 + Ext3 + Swap

ROM: Oxygen 2.0

Kernel: thalamus kernel-2.6.35.11_r2

Radio: 32.49.00.32U_5.11.05.27 (came with my early-2011 SLCD Desire)

running services

LauncherPro+ (5 homesccreens, 10 widgets in total)

Beautiful Widgets (1 weather/clock with unlock animations)

SwitchPro Widget (1 widget)

Swiftkey (1 dictionary)

SetCPU (245-998 ondemand, 245-499 ondemand screen off)

Stable. Good battery life - will easily last my working day (7-5). Nice solid ROM.

Only issues: I'm experiencing a few slowdowns. Swiftkey sometimes becomes sluggish and so does scrolling. 3G/HSPA connection occasionally does not transfer data even though it appears to be connected.

On the whole really nice. Definitely fewer FC and crashes compared to the RCs.

Gonna switch to the following and see how things go.

Kernel: thalamus kernel-2.6.37.2_r2

Radio: 32.44.00.32U_5.09.05.30_2

wiped dalvik, cache and battery stats again.

I think the radio is recommended for the RCs, and probably works better with this ROM than say the newer ones.
[Desire Android Development] Hosern1:
Hmm for me it was runing laggy with launcher pro. Using original kernel it is much smoother.

I've been getting some odd hangups, I'll be loading a webpage or starting an app and the phone will become unresponsive. Anything happening on the screen will still happen, (IE the loading graphic in the browser will still spin, but nothing else will change.) No buttons do anything, but eventually the screen will turn off and I can wake it by pressing the power button, but at that point I can't unlock the screen, my presses on the screen seem to be ignored. I have to pull the battery to get it to work again.

It is just standard 2.0, no mods or anything installed.

[Desire Android Development] z4ppy:
So effectively, I've pretty much just lost all those photos and videos then, without possible means of recovering/restoring?
[Desire Android Development] :
Well, you could try running something like Recuva to see if it will recover the files. But do it quickly, because the more stuff that gets written to the SDcard, the less stuff you will be able to recover.
[Desire Android Development] z4ppy:
Okay thanks. Ironically my internet has bloody died on me and has been out for the last 20 min. So will have to do this tomorrow. Hopefully able to get most of it back. Le sigh!

Oxygen 2.1.3 Installed with full wipe, without change the kernel.

[Desire Android Development] :
Yeah, make sure your SDcard is mounted.
[Desire Android Development] nava88:
Yes, I'm sure, I can see the content of my SDCard with a file explorer, but when I go to install an app the mobile phone suffers a soft-reboot (oxygen loading screen)

And I can download some file from internet, so the SDcard isn't in Read-only mode. Only fail when I install app's
[Desire Android Development] Shiftone:
Still convinced you've not formated and wiped everything properly.

If not that then SDCard corrupt. I had the same behaviour when I was sent a fake 16gb card.
[Desire Android Development] :
Delete the /sdcard/.cache directory. It'll be recreated when you try your next download.

If that doesn't work, you'll have to open an issue on the issue tracker and provide some logs.

No problems whatsoever.

I have over 100 apps installed and have suffered no FCs, slow-downs, reboots, nothing.

Coming from 1.0.4, this ROM is so much quicker and I'm getting improved battery length as well over 1.0.4.

GPS issues with r4 kernel

Thalamus,

I found wrong behaviour in r4 kernel regarding GPS. Today I can not connect to GPS, I see in Aura something like changing alternatively Satelites but no fix, this as during 5 minutes.

A more extensive testing and going back to standard radio (...05.27) did not solve the issue so I go back to 2.1.2 and the issue is solved.

This is a extrange beheviour as this does not happen always, in deed this night was the first one (in three days) with this kind of error, but even rebooting did not solve the issue.

Basically what happens (what I saw) was not fixing to any satelite, can see them but it was disconnecting from them every second, looking for other satelites but not been able to maintain connections with the ones alreadly seen.

AS I said this was not happening with 2.1.2 nor stock Froyo (at least did not happend to my phone in any situation).

Regards,

Mgmate.
[Desire Android Development] :
And you are certain that is a kernel issue?

Thats awfully strange and quite impossible as the kernel has absolutely nothing to do with gps.

The gps works by a load of RPC calls between android and the radio, which the kernel has absolutely nothing to do with.

It's quite likely that it's to do with that 2.2.1003G RIL you have in your signature tbh...

I don't understand why people feel the need to flash RIL packages and then complain that something doesn't work...it's quite frustrating.
[Desire Android Development] z4ppy:
Done this just then. Recovered some stuff, other photos that were found seem to be corrupted and no good.

I'll restore what I want on to the SDcard again now and things like icons etc I can extract again and copy back over when needed.

Am I able to delete the files within the LOST.DIR folder now? Since they're of no real use and aren't going to restore themselves.

Hopefully isn't something that happens again.

Also would it be wise to reformat the SDcard after this has happened or won't really make much of a difference and should be okay to continue using as is?
[Desire Android Development] :
I would probably reformat personally. Fat32 isn't the most robust filesystem at the best of times and there could still be underlying filesystem corruption which could cause the same issue again.
[Desire Android Development] mgmate:
Thalamus,

For sure I can not ensure that is a kernel issue but 2.1.2 works fine (well get connection, then disconnect and connect again -allways the same- but works and I have never had this issue, just plain not connecting to GPS..). But is weird issue as I said before as this only happens once for me, but repeated after even reboot the phone.

My signature is weeks ago before looking the more stable platform and follows your recomendation of not changing RILS and RADIOS... The used RIL is the one that comes with stock 2.1.3 oxygen, I think was 2.2.1001G. No change and the Radio was the stock also, 5.11.05.27.

Please let me know if I could help send you something to find where the issue is.. if i go forward with 2.1.3 again...

Regards,

Manuel.

PD: The reason to go up was regarding the also weird issue that after connecting to wifi during the night does not connect to Mobile data network again if not changing to 2G-3G or plane mode. But this is also happening in 2.1.3. :( it seems is something related with some chips which MAC address starts by 38:E7.
[Desire Android Development] :
You could check the issue tracker and you will find a few other people with the same issue. http://code.google.com/p/oxygen-rom/issues/detail?id=685

Without doing extensive search, I agree that, for the first time since 1year, I have problems with the gps the way you describe it. I flashed kernel R4 but seems not solving the issue, maybe a litte better.

I did not change the RIL but uses radio 5.14.05.17 (which was working perfectly since months). Altrough I cannot flash back the 5.11.05.27 (I'm on holidays far away from home) to make further test I think my post helps to make further investigations. I think it's maybe the V 2.1.3 who come with this but.

As for the wifi disconnecting 3G data with MAC address starting by 38:E7. It's a bug I encounter for ages on all kind of roms. this bug is also well known but unfortunately, no solution until now... I keep trying other radios hoping that one day it solves this bug.

It just seems it was solved on Defrost 2.4d but the bug goes back later http://xdaforums.com/showthread.php?p=7296769#post7296769

my workaround has been to automate wifi disconnection after 30min and scheduling wifi on/off with sync enabled each hour (using Settingprofiles)

Just wanted to say that I've come back to this rom. It's super quick compared to others I've tried. Even with all the fancy graphics enabled.

I've installed GoLauncher as the launcher. It's free and looks really pretty along with those graphics options it makes this rom very nice.

So thanks to the devs on this :)

I also like how the rom is like under 60MB, how is that even possible :)
[Desire Android Development] :
How many times do I have to say that GPS is *nothing* at all to do with the kernel. I said it a few posts before yours. How many more times do I have to say it before it finally sinks in?

Of course r4 won't solve the issue, and it won't make it any better either, because it has *nothing* to do with it. :eek:

GPS Issue Fixed.

OK, I posted about a GPS issue I had where by GPS signal would lock on for a few seconds and then appear to drop out for a few seconds and keep repeating. This caused a lot of problems with GPS software such as Google maps etc where the position would update every 5 seconds or so, basically causing no update then your position would jump 5 seconds later.

I was running an old radio (32.44.00.32H_5.09.05.30_2) which had been recommended, it was suggested to update 5.11.05.27 which I did. This improved things where by the lock seemed to be maintained, but the update period on navigation software remained at every 5 seconds or so. I downloaded GPS test and noticed that the satellite signal strength and number of satellites was updating quickly (about every second) but the time was only updating every 5 seconds or so. I assume the navigation software only triggers a read new position when the time changes hence the position would jump on the maps every 5 seconds.

Inspired by the suggestion to update the radio and seeing an improvement, I have just downloaded and flashed a later one 32.54.00.32U_5.14.05.17. I have run GPS test again and the time now updates every second. I have tried several GPS programs and they all now show the current position continually, no jumping about/updating every 5 seconds or so.

So updating my Radio has definitely 100% fixed my GPS issue. I am not a programmer, have no idea what is going on under the bonnet. I only know that this was NOT a rom issue (had the same on Redux) or Kernel issue (Roms use different ones)

The signal strength of the satellites has not changed, typically in the yellow at 33 to 37%. Hot fix time on Oxygen 12 seconds!

Another thought - flashing new radio and rebooting would have cleared initially the AGPS data - any issue there? Dunno.

Posting this in the hope it may help others.
[Desire Android Development] sjauquet:
Of course I read your post, I just write that to "confirm" that flashing an other kernel changes nothing.

I flashed the R4 before you wrote that it will change nothing, not being aware it was not related.

Devnull and Oxygen are basically idential, bar extra languages, locale support and a few additional mods in Oxygen which have *no* bearing on battery use. ;)
